silvia s12 and the vg30

[mistert]

ok im considering the purchase of one 1987 200sx SE hatch (the silvia s12/gazelle, for those of you who dont know). ill fill you guys in...in 87-88, for some reason (God knows why) nissan decided to sell an SE version of the 200sx, which included the vg30e engine out of the N/A Z31, as well as its transmission and rear end, and included 5 lug wheels. this was ONLY sold in the US (not in australia, japan, or anywhere else in north america). anyways, i have some questions relating to the N/A Z31, since the engine bay and all the hardware and mounts are the same as this car

1. can you transplant the turbo and manifolds and piping from a vg30et onto an N/A Z31
2. is the transmission the same as the turbo Z31, and how much abuse will it take
3. what kind of rear end would be on the N/A Z31 (I would assume r200 VLSD?)
4. is the vg30dett a direct swap into a z31 (and how much work is required)
5. is a DOHC head transplant a possibility, better yet, feasible
6. how much HP can you get ouf of a vg30e without internals and headwork (just the basic boltons)
7. how much hp can you get out of a vg30et without cracking the sucker open

i know we have some guys on here that are very knowledgeable about turbo z31's, as well as N/A z31's, so please, someone help me out here

I could also use a little more general info on the 84-88 200sx/Silvia S12/Gazelle, as information seems somewhat hard to come by

thanks for your time
